I haven't tried to use OCR on my phone for a while,, other than really basic stuff. When I tried to scan two pages of a book today with my old KNFB reader, I discovered that it doesn't play nicely unless you are using Samantha in IOS 14.5, and even then it isn't all that great anymore. It looks like they stopped supporting this one a long time ago, switched to an enterprise version, and I can't even tell if that is currently supported.
My question is: what is out there that supports multiple columns, allows saving of multiple pages, and can maybe do work to improve things like scanning a double page spread of a book? The iPhone camera is good enough to do a nice job for complex scanning, if there was just some powerful software to support it.
